server: add an error feedback mechanism for when the daemon fails to launch There's a recurring problem on Windows where `hg serve -d` will randomly fail to spawn a detached process. The reason for the failure is completely hidden, and it takes hours to get a single failure on my laptop. All this does is redirect stdout/stderr of the child to a file until the lock file is freed, and then the parent dumps it out if it fails to spawn. I chose to put the output into the lock file because that is always cleaned up. There's no way to report errors after that anyway. On Windows, killdaemons.py is roughly `kill -9`, so this ensures that junk won't pile up. This may end up being a case of EADDRINUSE. At least that's what I saw spit out a few times (among other odd errors and missing output on Windows). But I also managed to get the same thing on Fedora 26 by running test-hgwebdir.t with --loop -j10 for several hours. Running `netstat` immediately after killing that run printed a wall of sockets in the TIME_WAIT state, which were gone a couple seconds later. I couldn't match up ports that failed, because --loop doesn't print out the message about the port that was used. So maybe the fix is to rotate the use of HGPORT[12] in the tests. But, let's collect some more data first.

'''command to view revision graphs from a shell (DEPRECATED)
The functionality of this extension has been include in core Mercurial
since version 2.3. Please use :hg:`log -G ...` instead.
This extension adds a --graph option to the incoming, outgoing and log
commands. When this options is given, an ASCII representation of the
